Cuttlefish remember What, When, and Where They Ate
by Ed Yong
Like octopuses and squid, cuttlefish are cephalopods—a group of animals known for their amazing colour-changing skin and sophisticated intelligence. Cuttlefish are separated from birds and mammals by almost a billion years of evolution. But Jozet-Alves, together with Clayton and Marion Bertin, has shown that they too can “keep track of what they have eaten, and where and how long ago they ate”.
They are also soft-bodied and nutritious, which puts them on the menu of virtually every major group of ocean predator. Cuttlefish deal with these manifold threats through camouflage, defensive ink, and just plain-old hiding. They spend more than 95 percent of their time hiding in safe places. When they do venture out to search for food, it pays them to be quick about it. “Cuttlefish live fast and die young. They live less than two years, but their size drastically increases between hatching and old age,” says Jozet-Alves. “They definitely need to be very efficient when foraging if they want to grow as fast as possible.”…

One of America’s Most Beautiful Snakes
Robert Horan of Georgia Department of Natural Resources found a late-season (12 - Nov.) four-foot Rainbow Snake (F. erytrogramma) recently. She was crossing a primitive road during daylight, and Robert posed her nicely here—-at the edge of an Altamaha River swamp. This non-venomous, primarily aquatic, wetland associated snake feeds on eels and aquatic salamanders.

This “cascade red fox" (Vulpes v. cascadensis) was spotted over the weekend at Mount Rainier National Park, in Washington state, USA, sporting a unique coat. The mixed charcoal and reddish coloration is typical of the red fox population in the park.

The scaly foot gastropod is probably the worst snail name ever invented. Especially for one of the most incredible organisms on the planet. How many creatures can you name that have an iron shell? None. No creature can grow a metal sheath around itself—except Scaly G. Living nearly 2,400 meters (8,000 ft) below the ocean’s surface, near hydrothermal vents, the scaly foot gastropod incorporates the heavy metals floating in its habitat into its shell.
this is the most metal thing I’ve ever seen
